Forward all mail in mbox to new email address

["ThanhVu Nguyen (Yahoo)" <nguyenthanhvuh@yahoo.com>]

I have a large number of emails stored in a mbox file
and I read these mails from mutt.  I'd like to forward
*each* one of them to a new email address (not as a
big attachment).  I can forward one by one manually
but I am looking for a way that automates this
process. Anyone can help me out here ?   


Thanks ,  

PS: it would be much better to have these sent to the
new address with the senders are the original ones
instead of me, but if it's not possible, forward would
be fine.
